Defender help please

Hi all,

I am about to restore a 200tdi 110 defender. I want to sit it on a yet to be sourced galv chassis with replacement bulkhead (also to be sourced and galvanised). Does anyone know if a all defender bulkheads are interchangeable? This would give me more purchase options because I could then choose between TD5, 300 TDi and 200TDi.

If you have a good bulkhead or 200TDi or 300TDi chassisI would also like to hear from you.

Michael
